Abstract

A cost-effective transmission line safety monitoring system which detects and tracks acoustic and chemical anomalies along a transmission line to determine if a destructive event is present. One or more sensors, each enclosed in a weather-resistant container, are attached to an antenna and installed as part of the antenna transmitting system on a tower, building top or hill. The acoustic signatures and gas purity deviations are detected and transmitted to a remote master processing center where, via the use of packaged software, the signals are continuously compared to an existing library of acceptable and non-acceptable signatures for pattern matches. An operator, using a PC in a simple WINDOWS® format, may assign newly acquired signatures to the library for future operation. Different levels of alarms may be triggered and a system shutdown may be initiated, if the incoming signals are similar to or directly match one of the pre-entered non-acceptable signatures, or alternatively, if the gas purity levels are exceeded.

Claims

1. An apparatus for detecting and monitoring system anomalies along a transmission line comprising:

a plurality of detectors situated along a transmission line, said detectors to monitor acoustic signatures of audio signals along said transmission line;

a processing unit disposed at a location remote from said detectors;

means for transmitting said audio signal to said processing unit; and

means for comparing said transmitted audio signals to a database of permissible and non-permissible sounds to determine if said audio signals qualify as a destructive event; and

each said detector is comprised of an acoustic detector module which detects said analog signals, digitizes said signals, and transmits said signals via a data packet to said remote processing unit wherein said digitized signals are encoded with a number corresponding to the detector'"'"'s location along said transmission line, and a gas product detector module for monitoring the pressurized environment within said transmission line which creates a linear quality word representing gas purity within said transmission line, said linear quality word is embedded into said data packet and transmitted to said remote processing unit, wherein said linear quality word representing gas purity within said transmission line contains a number corresponding to the detector'"'"'s location along said transmission line.

2. The apparatus of claim 1 further including one or more alarm triggering means wherein the presence of said destructive event triggers one or more alarms to signify the presence of an anomaly wherein the severity of said anomaly determines which said alarm will be triggered.
